Round 7: response to reviewers
Protocol version reviewed: 0.7.0. Revised version: 0.8.0.
Verdicts: GPT-6 Astra MINOR REVISION; Fable 5.1 ACCEPT; Grok 4.7 MAJOR REVISION (one major item, also raised as minor by the other two reviewers). Every comment is answered below and recorded in ../comments.csv.
Summary of main changes
- All cause mortality (O20): hazard ratios and complete status counts share one not applicable network; counts for outcomes with competing events go only to subdistribution networks.
- Conclusions rule extended to time to event outcomes; 95 percent sensitivity counts assigned a hazard type.
- Competing risks: Kaplan-Meier contrast estimator; time varying integral; conversion fallbacks per hazard type; who judges nonproportionality and constant hazards, and when.
- Absolute effects: no single rate reference risk for outcomes with competing events; data items for the competing hazard; recorded harms offset written as log t.
GPT-6 Astra (gpt-6-astra)
C7-1 (minor; Competing risks). Absolute effect fallback overrides valid conversions.
Response (revised). Agreed; your replacement adopted (cause specific: relative only when neither integration nor a supported exponential approximation is possible; subdistribution: reference cumulative incidence and proportional subdistribution hazards, without constant cause specific hazards).
C7-2 (minor; Event outcomes and harms; O20). Count routing conflicts with all cause mortality.
Response (revised). Agreed (grok-4.7 G7-M1 and fable-5.1 F7-2 raised the same point). Counts for outcomes with a competing event enter only the subdistribution network; for outcomes without one (at present only O20), hazard ratios and complete status counts share the not applicable network, which is primary.
C7-3 (minor; Recorded harms analysis). Offset written as t instead of log t.
Response (revised). Agreed; corrected.
Fable 5.1 (fable-5.1)
F7-1 (minor; Absolute effects). Constant hazard reference risk is a net risk for outcomes with competing events.
Response (revised). Agreed. For outcomes with competing events a single event rate is never used: the reference risk is the reported Aalen-Johansen cumulative incidence, otherwise the exponential competing risks expression from the pooled rates (which then serves as F_ref), otherwise the relative only rule. This also answers grok-4.7 G7-4.
F7-2 (minor; Time to event counts). Downstream sentences for time to event counts.
Response (revised). Agreed; your three replacements adopted (conclusions for time to event outcomes with descriptive reporting as the last step, likelihood list, sensitivity list).
F7-3 (minor; Data items). Items needed for the competing hazard.
Response (revised). Agreed; competing deaths without a preceding target event, person years by arm (with the stated fallback) and any reported competing event hazard ratio are now data items.
F7-4 (minor; Competing risks). Two judgments without criterion or timing.
Response (revised). Agreed; your replacement adopted (two reviewers, before relative effects are modeled, logged with reasons, with the stated criteria and the alternative as a sensitivity analysis).
F7-5 (minor; Competing risks). Not applicable set open.
Response (revised). Agreed; at present only O20.
Grok 4.7 (grok-4.7)
G7-M1 (major; Event outcomes and harms; O20). Count sentence contradicts the not applicable rule for all cause mortality.
Response (revised). Agreed; your replacement adopted (see C7-2).
G7-1 (minor; Competing risks). Time varying integral omits where the hazard ratio enters.
Response (revised). Agreed; your sentence adopted (the hazard ratio enters inside the integral and inside all cause survival).
G7-2 (minor; Competing risks). Kaplan-Meier contrast has no stated estimator.
Response (revised). Agreed; it enters as the contrast of log(-log S) at a common t with a delta method standard error, only when 0 < 1 - S < 1, without continuity correction in the contribution network.
G7-3 (minor; Conclusions; 95 percent sensitivity). Conclusion order for time to event outcomes; hazard type of sensitivity counts.
Response (revised). Agreed; conclusions now cover time to event outcomes (cause specific network primary, then subdistribution labeled, then descriptive reporting) and the 95 percent counts are a sensitivity analysis of the subdistribution network (or the not applicable network for O20), never of a cause specific network.
G7-4 (minor; Absolute effects). Single rate fallback for outcomes with competing events.
Response (revised). Agreed; see F7-1. Reported Aalen-Johansen incidence first, then the exponential competing risks expression from both pooled rates, otherwise the relative only rule.
